no, it doesn't. compiler doesn't know about `std.format.format` and it's 
special abilities. while it is possible to add such checks to the 
compiler, it will introduce interdependency between compiler and phobos, 
which is not desirable.

writing CTFE `writef` version is possible without template bloat in 
binary, but it will take more memory in compile time and slows 
compilation. there were talks about having `writef!"fmt"(args)` in phobos, 
but nobody took that task yet.
